How Complete Off Grid Solar Power Systems Work

Solar panels contain photovoltaic cells made of silicon that convert photons from sunlight into direct current (DC) electricity. This solar-generated power flows to a charge controller which regulates the voltage to prevent overcharging the batteries. The DC electricity is then stored in a large solar battery bank to provide renewable off grid power day and night. When electricity is needed for use, a power inverter transforms the DC current from the batteries into 120/240V alternating current (AC) to run all the lights, appliances, devices and equipment on the off grid homestead.
